This form, characterized by a distinctly serrated collar, large gular 

 and dorsal scales, a low number of femoral poi-es, bears some resem- 

 blance to L. derjugini. 



Shape of head and proportions exactly as in the typical fonn of 

 L. muralis ; hind limb reaching the shoulder or the collar in the male, 

 the elbow of the adpi'essed fore limb in the female. 



Eostral not touching the nostril, usually separated from the fronto- 

 nasal''' ; nasal sometimes forming a suture with the anterior lorealf ; 

 granules between the supraoculars and the superciliaries forming a 

 complete or incomplete series, or even reduced to three ; occipital 

 mvich shorter but sometimes broader than the interparietal ; antero- 

 lateral notch of parietal present or absent^ ; anterior supi-atemporal 

 usually in contact with the fovirth supraocular§ ; temporal scales 

 granular, II tympanic shield large, masseteric large or moderate; three 

 or four upper labials anterior to the subocular. Gular fold feeble or 

 absent ; edge of collar more or less distinctly serrated.^f 



Dorsal scales round or oval-hexagonal, smooth or faintly keeled, 30 

 to 42 corresponding to the length of the head, 2 or 3 or 3 or 4 to one 

 ventral plate. Preanal with one semicircle of small plates. Scales 

 on upper surface of tibia feebly keeled, smaller than dorsals. Caudal 

 scales forming alternately longer and shorter whorls, diagonal, more 

 or less strongly keeled, truncate or obtusely pointed behind, 26 to 30 in 

 the fourth whorl behindjpostanal granules. 



Brownish or olive above, with paired series of blackish spots, which 

 are crowded on a dark lateral band extending from the temple to the 

 root of the tail ; above and below this a light streak is usually present, 

 the upper of great width in the specimen from Mt. Fatguss ; lower 

 parts white or greenish, in spirit ; a series of small blue spots on the 

 outer row of ventrals. 



* Forming a narrow suture with the frontonasal in the specimen from Dariel 

 Gorge.
